mum number of parts, and with a minimum amount of manual manipulation.Inone form of our invention, we use a rotary bolt, and in a furthermodification. we use aconventional bolt of the sliding type. While thesliding type of bolt 'is' conventional in that More particularly, theinvention; relates to a lock of the class described in which certainoperations may be obtained with a'miniof the sliding type of latch boltagainstretraction to open the door, except when certain means areoperated from either the outside or the inside of the door, and when'thedoor is slammed shut. As an important feature of our invention, wearrange for the dogging of the outside operated means, which in thiscase is a push button, by the inside operated means, which in this caseis a lever. Moreover, the same lever that dogs the outside push buttonagainst operation, itself releases the latch bolt for retraction whenoperated in a particular manner.

As a further feature of our invention, we arrange for the releasing ofthe dogging of the outside operated button when the door is slammedshut, should the button be dogged'with the door in open position. Asstill a further feature of the invention, it is possible to assemble thelock relatively to the door and the usual sliding glass window, withoutthe employment of relatively costly mechanism heretofore required foravoiding obstructing the window operation; All of this will be clear tothose skilled in the art.

More in detail, the sliding bolt modification of our invention comprisesa bolt which isspring projected into locking position, this boltcooperating with a strike whereby it latches back and forth until itreaches a locking position. The

strike and bolt are so designed that a reverse pressure on the bolt bythe strike is adapted to retract the latch so that the door may beopened.

' For preventing the retraction of thelatch in this manner, we use adogging membenwhich in our preferred embodiment is a slide member, andthis slide may be retracted from dogging pos tion by an inside operatedlever, or by an outside operated lever. The inside operated lever,moreover, may dog the outside operated lever.

. latchback, we utilize a very unique and novel mechanism-for moving thedog ng slide out or dogging relation 'to the boltas the door is swungthat. This mechanism, in apreferredform, comprisesfan auxiliary boltmember which is ro- .tatablyj,,mounted, preferably 'on the bolt itself,an'dwhichj impinges asamstthe strike in ad varice'of 'thebolt, Whenso'impinging, it rotates v and n'lovesthe slide-vertically and out o.fdog'-. m retractive movement of the bolt itself which fol--'lo'wsimmediately'thereafteni Because of the natureof our construction,we"

The mounting of the outside operated levris such on theend plate that'the glass may come into juxtaposition to the endi "platewithout interfering with the operation of the lock. f 1

In the second modification of our invention, we utilize a rotating boltwhich is" dogged against rotation in an unlocking direction by a slide,very similar to the slide in the first modification. Because of thenature of the bolt, the bolt itself retracts the slide in a latchingmanner toallow the bolt to move into locked relation to the strike.Reverse rotation of the-bolt, however, is prevented by the slide member,and toallow this reverse rotation, it is necessary to retract the slidemember by the inside or the outside lever,

much as in the first modification.

Of course, the inside and outside levers control one another as in thefirst modification. We utilize the latching back or retracting of thesliding dog member by the latch bolt as it moves into locked relation tothe strike to release the outside lever from the inside lever, much asin the first modification; We have. thus described the two modificationsof our invention generally, because we believe that this generaldescription will be helpful in a proper appreciation of the detailedstructure which follows.

In describing our invention in detail, we shall. refer-- to the'drawingswherein Fig. 1 is an elevation showing our rotary bolt lock.and its relation to the operating structure. Figs. 2 and 3 are sectionstaken along lines 22 and 3-3 of Fig. 1.

the particular structure.

For convenience, we shall first describe the sliding bolt lock of ourinvention. Referring now to Figs. 7-12, inclusive, and especially toFigs. 7 and 12, the frame of our lock is an L shaped member having abase plate portion l0, and an end plate portion ll. ofa nose l2 rivetedat l3 to a tail H, the tail extending at I5 into a bearing member l6carried on the base plate |0.- The nose of the bolt extends through anopening H in the end plate II, this opening l1 and the bearing l6 actingas guides for the bolt assembly. A coil spring l8 projects the boltoutwardly from the lock, this projection being limited-by a lug IS onthe bolt tail |4 cooperating with a rubber lug 20. In Fig. 12, forconvenience, thebase and end plates l0 and II respectively are notshown, nor is the tail of the bolt, only the nose l2 and the rivets l3being illustrated.

For locking the bolt |2 against retraction, I

employ a dogging slide 2| cut away at 22 for support on a pair of studs23 and 24 extending from the base plate M. A spring 25 presses on thesurface 26 of the slide 2|, and maintains it in its position of Figs. '7and 12 in dogging relation to the bolt l2, with .its portion 2 la behindthe shoulder |2a of the bolt.

An inside operated lever 21 is pivoted at 28 to the base plate I0, andhas a portion 29 impinging against 9. lug 30 struck from the slide 2!.When the lever 21 rotates in a.counterclockwise direction in Figs. 7 and12, it moves the dogging slide 2| out of dogging relation to the boltl2. A

spring 3| cooperates with either one of two depressions 32 of a plate 33forming part of the lever 21 for yieldingly holding the lever 21 in itsposition of Figs. 7 and 12, or in the positionof Fig. 11 clockwise fromits position of Figs. 7 and 12, in which position it performs a furtherfunction, to be described presently.

The end plate II has pivoted thereto at 35 a lever 36 which has an arm31 adapted to be contacted and operated by a push button, to bedescribed presently, which push button is mounted on the outside of thedoor, and which rotates the lever 36 about its mounting 35. The arm 38of the lever 36 is adapted through contact at point 33 with the slide2|, to move the dogging slide out of dogging position in the same manneras it is moved by inside lever 21.

' The lever 36' has a further arm 40, and it is through this arm 40 thatthe lever 36 is dogged against operation by the arm 4| of the lever 21.Thus, when the lever 21 is rotated in a clockwise direction from itspositions of Figs. 'I and 12, the arm 4| thereof moves in behind the arm40, as shown in Fig. 11, and blocks rotation of the lever 36 intended tomove the dogging slide 2| out of dogging position.

Because of this relation of the-parts, the lever 21 may rotate in onedirection about pivot 28 to retract the slide 2|, and may rotate inanother direction to block the operation of the outside lever 36 so asto prevent release of the locking mechanism from the outside ofthe car,thus contributing a form of protection which is valuable in this type oflock.

Glancing now at Fig. 12, it that the bolt I2 is dogged againstretractive movement, and were the door slammed into shut position withno means present for retracting the dogging slide 2|, the door could notbe shut except by operation limultaneomly of one of. the

The bolt isformed will be appreciated Fig. 12 is a perspective view ofessential parts of levers 21 or 36. To allow the door to be slammed shutwithout operation of either the inside or outside levers, we utilize anauxiliary bolt 42 which is preferably pivoted at 43 on the bolt l2, andwhich has a tail 44 impinging against a cam piece 45 stamped out of thedogging slide 2|. This auxiliary bolt 42 is adapted to contact thestrike with which the bolt l2 cooperates, in advance of the bolt l2, asis probably best illustrated in Figs. 8 and 10. In Fig. 8, the strike isdesignated by reference numeral 46, and has two locking portions 41 and48, so as to give a double locking action which is deemed necessary inthe art.

As the door is swung shut, the auxiliary bolt 42 first impinges againstthe strike and moves on its pivot 43, acting through its tail 44 and cam45 to move the slide 2| upwardly and out of deadlocking relation to thebolt |2. This movement is repeated for the second locking at 48, aswill,

be understood, thus bringing'the parts to the locking positionillustrated in Fig. 8, all as is quite apparent.

We have found it desirable to provide means for releasing the outsidelever 36, should that lever be locked against movement when the door isopen, and the door then slammed shut. This is to prevent a locking outof the owner of the car. In order to describe this action, let us assumethat the lever 21 has been rotated about its pivot 28 to bring itsportion 4| in obstructing relation to the arm 40 of the lever 36, thatis, to the position of Fig. 11. This, it will be noted, brings a campiece 49 of lever 21 in rather close relation to a surface 50 on thebolt tail l4, all as is shown in Fig. 11.

Now, should the door be slammed and the auxiliary bolt 42 perform thefunction of moving the slide 2| out of dogging relation to the main boltl2, the retractive movement of the main bolt will through cobperationofthe surfaces 48 and 50, rotate the lever 21 back to its position ofFigs. 7 and 12, or out of locking relation to the arm 40 of lever 36.This, of course, releases the lever 36 for operation from the outside,all as will i be clear.

For rotating the lever 21, about its pivot 28, we may use a standardtype of remote control mechanism, although any other type of mechanismis For convenience, we have shown a rotating lever 5| connected througharm 52 and lever 53 to the lever. 21, it being obvious that rotationofthe lever 5| by a suitable handle against the pressure of 'a'controlspring 54 will serve to rotate the lever 21 either into a position toretract the dogging slide 2| from dogging position, or to rotate thelever 21 into position dogging the outside release mechanism againstoperation.

For rotating the lever 36 on its pivot 35 to move the dogging slide 2|out of dogging relation to'bolt l2, we utilize a push button 55, or acylinder lock '55, as the case may be. In three doors of a four doorsedan, we use a push button, but in the fourth door, we use a cylinderlock. In principle, this follows thepractice in the automobile industrytoday. As is illustrated in Fig. 8, the cylinder lock 55 is locked fromthe outside by therotation of a cam 56 thereon which interlocks at.56awith a sleeve 51 forming part'of the outer surface 58 of the door. Thismaintains the cylinder 55 against inward sliding movement necessary tooperate'lever 36. When the cam part 56 is out of the notch 56a of thesleeve 51, the cylinder 55 may slide inwardly in Figs. 8

and 9 and rotate the lever 36, all as is quite apparent. In the case ofthe push button used on three of the doors, it will be possible alwaysto apply pressure to the lever 36, but it will be impossible to rotatethe lever 36 when it is locked by the arm ll of lever 21 from theinside.

We have now described the operation of bolt l2 and its locking by theslide 2|. We shall now describe how the bolt I2 is retracted from itslocked position of .Fig. 8-to permit the opening of the door. Grantedthat in Fig. 8 the dogging slide 2! is'moved to releasethe bolt l2, itis necessary to 'understand how the bolt is retracted.

the bolt 62 and itspart 65 rotate in a locking direction, it beingobvious that the slide will move up and downuntil, when the bolt is inthe position of Fig. 2, theparts will assume the position of- Fig. 6. Aswas explained previously, reverse rotation of bolt-62 is of courseprevented with theparts in the position of Fig. 6.-

If the door is open and the lever H is moved into position to lock thelever 36 against rota- Examination of bolt l2 will illustrate that it isI beveled-on both sides in such a manner that it will cooperate with thestrike surfaces 41 and 48 in a manner to force the bolt l2 rearwardlyagainst the pressure of its spring l6 when a pull is exerted on theoutside handle 59, or when pressureis exerted against the door from theinside in the direction of the arrow 66' in Fig. .8. The,

operation from the outside will be as follows:

This upward movement Should the ;1ever 36 notbe dogged from the inside by an occupant of the car, pressurev on" pushbuttonorlock cylinder 55 from the outside rotate thelever 36, causing-ittomove dogging slide 2| out of dogging position. A-pull on the, handle59 will now. cam the bolt l2 back, opening all ofwhich will of course beapparent to those who have studied the particular problem, and

who know of the, many costly mechanisms which have been developed tomake possible a narrow window frame.

Weshall now refer to Figs. 1 6, inclusive, wherein we show a form of ourinvention in which we utilize a rotary latch bolt 62 formed with fourteeth 63, and mountedfor rotation on end plate II on the axis of a shaft66. The shape of the bolt 62 and its teeth 63 is probably bestillustrated in Fig; 2a. Secured on the shaft 64 for rotation. therewithsimultaneously with bolt 62 is member 65 having teeth 66 shapedsimilarly, but

not exactly like teeth 63 of bolt 62.

In Figs. 2a and 3, there is shown at 6'! a strike having portions 68adapted to interlockwith the teeth 63 of the bolt 62. The operation ofbolt 62 and the member 65 is such that the two parts 62 and 65 mayrotate freely in a.direction to interlock the bolt and strike, that is,to the position of Fig. 2. A reverse rotation of the bolt 62 and itspart 65 is prevented by a lug 69 on a dogging slide 70, which is similartodogging slide 2! in most particulars. mounted on thebase plate I0, issimilarly spring pressed in a locking direction, and is similarlyretracted out of dogging position through a lever 'H, which is almostidentical with lever 2! of my first modification.

The lever Ii acts to lock a lever 36 against operation from the outsideexactly the same way as in the first modification described (Figs. 4 and5). The lever 36 in turn retracts the dogging slide 10 in the samemanner as in the first modification through the use of arm 38. Forthrowing oi! the locking of the lever 36 by the lever '|l,'we'.utilizeThus, the slide 16 is similarly F s. 4 and 5 ,ouite apparent,- e I V Thelever' ll is-controlled much: in the same manner'as is the lever 21 ofthe first modificawill cause the uppersurface 12 of the lug 63 to abutthe under surface .13 of the arm ll of lever.

Rotation of the handle I5 into the position markeddeadlocked, wfll, through 1 suitable means rotate the lever II into itsdot and dash line position of Fig. 1, in which position the outsideoperated lever 36 will'be locked againstoperation. If, on the otherhand, the handle 15 is rotated into unlocking position, 'the slide."

will be moved vertically from the position of Fig. 6, releasing themember 65 for rotation. This, of course, releases the bolt 62 forrotation to release position.

The outside operated lever first modification. When the push button 55operates lever 36, a pull on the handle 59, which is exactly like thehandle of the first modification, causes a rotation of the bolt 62,allowing the a construction which is but slightly different in detailfrom that of the first modification. The
